Abstract

The influence of DC Joule heating treatment on the longitudinally driven giant magneto-impedance (GMI)effect of Fe₃₆Co₃₆Nb₄Si_4.8B_19.2 ribbons was studied, and the GMI effect responded sensitively (the sensitivity was as high as 2440.2%/A•m^-1) to weak magnetic field was detected after annealed at current density of 3.2×10⁷A/m² for 600-second. The experimental results showed that the sensitivity is closely related to annealing current density, driven current frequency and eroded thickness.
